Summary

Singapore · AI-generated

business corporate asia-pacific

The AS handle SONY-APAC-AP is held by Sony.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames GISSSES, GISSSES-AS-AP, and NETBLK-SONY-US and a reverse DNS entry for sony.co.jp.
  • The AS announces 6144 IPv4 addresses across 3 prefixes and 16 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate endpoints and services for Sony's Asia-Pacific operations, including office workers and internal web/API services.

Notable

  • Registrants align with the announcer, listing Sony Electronics (S) Pte. Ltd for the Singapore-based blocks and Sony Electronics Inc. for the US-based block.
  • The inventory is finely subdivided into three distinct IPv4 blocks and ten IPv6 prefixes, reflecting site-by-site segmentation typical of a large multinational corporation.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
